Position your oven rack to the middle and pre-heat to 350 F (see notes for microwave instructions).
Add chicken, cottage cheese, Greek yogurt, Buffalo sauce, garlic, black pepper, ⅓ cup green onions, and shredded cheese to a large mixing bowl. Mix until well combined.
Transfer Buffalo chicken dip to your baking pan. Use a spatula or large spoon to gently press and flatten your dip.
Top with more shredded cheddar cheese if desired.
Bake for 22-27 minutes or until cheese is melted and dip is bubbling. Top with remaining green onions before serving.
Microwave instructions: Add dip to a microwave-safe dish and cook for 2-3 minutes or until dip is heated through. I do not recommend topping your buffalo chicken dip with extra cheese if you're using the microwave since you may need to stir occasionally for even warming.
